Problems solved by technology

[0003] However, in practical work, it is often found that: ① the distance between the full buds on the scion varies greatly, and most of the full buds are densely distributed in the middle and upper parts of the scion. Sometimes the collected bud pieces with a length of about 3 cm often contain 5-6 full buds , which seriously wastes the scarce resources of fine seeds; ②After grafting 300-500 plants, the edge of the bud grafting knife will become blunt, which will not only take a lot of effort to get the buds, delay the work efficiency, but al

Embodiment 1

[0040] Embodiment 1: the grafting method of pecan walnut, comprises the steps:

[0041] 1) Selection of budding period: May 12th, a sunny day;

[0042] 2) Collection and storage of scions:

[0043] Select semi-lignified new shoots with strong buds as scions, and cut off the leaves immediately after collection, leaving 1 cm cm at the base of the petiole to protect the strong axillary buds, wrap the scions with a damp cloth and store them in a cool place, and graft on the same day;

[0044] 3) Grafting:

[0045] ①Choose a branch with a thickness of 0.6cm as the rootstock, and use a new budding knife to cut across the smooth part of the rootstock in the northeast direction. The width of the knife edge is roughly 1 / 3 of the thickness of the rootstock, and the depth reaches the xylem. Make a slit with the tip of the knife on the left or right side of the incision. When slitting, cut a wound opening with a length of 2cm and a width of 2mm at the same time below the incision. Spray...

Embodiment 2

[0053] Embodiment 2: the grafting method of pecan of thin shell, comprises the steps:

[0054] 1) Selection of budding period: September 12th is cloudy;

[0055] 2) Collection and storage of scions:

[0056] Select semi-lignified new shoots with strong buds as scions, and cut off the leaves immediately after collection, leaving 1.5cm at the base of the petiole to protect the thick axillary buds, wrap the scions with a damp cloth and store them in a cool place, and store them for more than 24 hours before grafting;

[0057] 3) Grafting:

[0058] ①Choose the trunk with a thickness of 0.8cm as the rootstock, and use a new budding knife to cut across the smooth part of the rootstock in the northeast direction. Make a slit with the tip of the knife on the left or right side of the incision, and then use the tip of one of the blades to make a slit on the left or right side of the incision. When slitting, cut a wound with a length of 2cm and a width of 2mm below the incision at the...

Abstract

The invention provides a dud grafting method for apocarya, and belongs to the technical field of plant vegetative propagation seedling culture. The method includes the following steps of bud grafting period selection, scion collection and storage, grafting, management conducted after grafting, stock pruning and the like, wherein a bud grafting knife limited by the method is adopted for scions. By using the novel bud grafting knife, the bud grafting utilization rate and the work efficiency are greatly increased; meanwhile, by using a browning prevention agent, tissue browning can be effectively relieved, smooth conduction of the bud grafting technology is facilitated, and the grafting survival rate is increased; the bud grafting method has the advantages of being easy to operate, high in efficiency, capable of fully utilizing cutting materials, stable in survival rate, and the like. The bud grafting method is also suitable for forest and fruit trees such as walnut trees, sophora japonica trees, persimmon trees and olive trees.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation and seedling cultivation, and in particular relates to a method for budding of pecans with thin shells. Background technique [0002] Thin-shelled hickory (Caryaillinoinensis Koch) is a plant of the genus Hickory in the family Juglandaceae and is a world-renowned dried fruit tree species. Grafting propagation is one of the most widely used vegetative propagation techniques in forestry production, especially the application of block bud grafting technology in the grafting of pecans, which enables the large-scale and rapid propagation of fine varieties of pecans to be realized. In the summer budding of thin-shelled pecans, the bud slices are generally cut with a traditional square budding knife, and the bud slices with a width of about 3 cm can have only one full bud body. [0003] However, in practical work, it is often found that: ① the distance between the full buds on the s...
